compose clj

(compose pred)

(compose pred1' pred2')

(compose pred1 pred2 & more)

Compose several predicates - can see this as intersection

cycle clj

(cycle grain)

A sequence of each year, or month, or week, etc. Used for 'this year', 'next month', 'last week'..

day-of-month clj

(day-of-month dom)

day-of-week clj

(day-of-week dow)

fn& clj macro

(fn& grain args & forms)

grain-after-shift clj

hour clj

(hour h twelve-hour-clock?)

intervals clj

(intervals pred-from pred-to inclusive-to?)

Builds a sequence of intervals, each starting at the start of pred-from and ending at the start (inclusive-to? false) or end (inclusive-to? true) of the first pred-from time that follows the start of pred-from. Example: (intervals (day-of-week 1) (day-of-week 3) true)

minute clj

(minute m)

month clj

(month mo)

my-mapcat clj

(my-mapcat f coll)

resolve clj

(resolve {:keys [dim pred not-immediate timezone] :as token}
         {:keys [reference-time] :as context})

Turns a token into a list of actual possible time values. Behavior depends on the ref-time in context, and token fields like :not-immediate.

safe-max clj

safe-max-interval clj

sec clj

(sec s)

seq-map clj

(seq-map f pred & [dont-reverse?])

Applies f to each interval yielded by pred. As f changes intervals, an interval that was ahead can become behind, and reciprocally. We make the assumption that f doesn't change the order of intervals though, or it would be much harder to maintain lazyness.

shift-duration clj

(shift-duration base-pred duration)

Shifts base-pred forward or backward ('two days after pred') Duration can be negative ('three hours before pred'). The resulting grain is the one just below the duration's grain Shifted slots' width is exactly their grain

show clj

(show f)

take-n clj

(take-n pred n & [opts])

Takes n cycles of pred. Used for 'next 2 weeks' for instance. Goes forward for positive n, backward otherwise.

Accepts a :not-immediate option like take-the-nth

take-the-last-of clj

(take-the-last-of cyclic-pred base-pred)

Takes the last occurence of cyclic-pred within base-pred. For example, cyclic-pred is 'Monday' and base-pred 'October'

take-the-nth clj

(take-the-nth pred n & [opts])

Builds a predicate with only the nth time slot of a presumably cyclical pred after ref-time, backward (negative n) or forward (positive n). Beware that 0 => first forward, but -1 => first backward

Options:

:not-immediate: if true, the first slot will be dropped if it contains t. No effect on backward lookups (t is never containes in them).

take-the-nth-after clj

(take-the-nth-after cyclic-pred base-pred n & [opts])

Like take-the-nth, but takes the nth cyclic-pred after base-pred (or before if n is negative. Since pred generates sequences, it also generates sequences.

Options: :not-immediate works as usual

year clj

(year yyyy)
